· We propose multi-loci and multi-site current patterning (sequential or
simultaneous) for precise, rapid and repeatable steering for improved
· Here we demonstrate these improvements by using a unique pixel cell
for excitation synthesis as enabled by a three-layer dense magnetic coil
array that is mapped to a hexagonal grid with cubic coordinates.
· We validate the theory with supporting simulations, experimental
results and a scalable electronics design that can address a relevant
range of larger coil diameters, higher power levels and topologies.
· Precise, rapid and repeatable patterns potentially offer new
modalities for noninvasive neuromodulation (suprathreshold and
subthreshold) and adjacent biomagnetic applications such as tumor cell
membrane disruption , and magnetic drug delivery .
